"Why don't you do your job, you fat b----!" Mahlke shouted in what prosecutors said was an unprovoked verbal onslaught Sunday. When the 19-year NYPD veteran asked for his license, Mahlke tried to maneuver his 2009 Honda Civic past her but she stopped him by stepping in front of his car, prosecutors said.

Mahlke then pulled out an official state Senate business placard and a forged police placard, trying to pull rank, they said.

"You don't know who I am," Mahlke reportedly told her. "I'm higher ranking than you. I work for Mayor Bloomberg."

She was having none of it.

Mahlke was charged with failing to obey a police officer and possessing a forged police placard. He also did not have a valid driver's license, police said.

Mahlke, who lives in Elmhurst, says he has been unemployed since his former boss was ousted from the state Senate in February - and rejected by voters a month later.

Monserrate's career imploded when he was found guilty of misdemeanor assault for slashing his girlfriend's face. Now Mahlke faces up to seven years in prison for his alleged abuse.
